Yes that what I do. And thanks to your doc, it help me a lot.
Now I want to test my server using sipP. 
Did you have an example xml for register and INVITE???

I have create a thousand user but I still cannot test my server using my xml.
This is my xml:
<?xml version="1.0" encoding="ISO-8859-1" ?>

<scenario name="register_client">
  <send retrans="500">
    <![CDATA[
      REGISTER sip:[field1] SIP/2.0
      Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]
      From: <sip:[field0]@[field1]>;tag=[call_number]
      To: <sip:[field0]@[field1]>
      Call-ID: [call_id]
      CSeq: 1 REGISTER
      Contact: sip:[field0]_[branch]@[local_ip]:[local_port]
      Max-Forwards: 5
      Expires: 3600
      User-Agent: SIPp/Linux
      Content-Length: 0
    ]]>
  </send>
